Customer cards are all blank in FireFox browser

[fangpenlin]

It seems somehow, the filter we are using for customer card makes them blank in FireFox browser:

filter: url("data:image/svg+xml;utf8,<svgxmlns=\'http://www.w3.org/2000/svg\'><filterid=\'grayscale\'><feColorMatrixtype=\'matrix\'values=\'0.33330.33330.3333000.33330.33330.3333000.33330.33330.33330000010\'/></filter></svg>#grayscale")

If I disable this style, it can then be displayed without a problem.

This is still not working, it appears the YUI Compressor remove spaces in that data URI, which makes it a malformed data image

filter: url("data:image/svg+xml;utf8,<svgxmlns=\"http://www.w3.org/2000/svg\"><filterid=\"grayscale\"><feColorMatrixtype=\"matrix\"values=\"0.33330.33330.3333000.33330.33330.3333000.33330.33330.33330000010\"/></filter></svg>#grayscale");

As you can see all spaces between tag name and attribute are gone.
